INSTRUCTIONS FOR INSTALLATION  
4. Attach a hose to the water heater  
Removing the Old Water Heater  
drain valve and put the other end  
in a floor drain or outdoors. Open  
the water heater drain valve  
(behind outer door). Open a nearby  
hot water faucet which will relieve  
pressure in the water heater and  
speed draining. The water passing  
out of the drain valve may be  
extremely hot. To avoid being  
scalded,  
make  
sure  
all  
connections are tight and that the  
water flow is directed away from  
any person, see Figures 1 and 4.  
FIGURE4.  
5. Disconnect the vent pipe from the draft hood where they  
connect to the water heater. In most installations the vent  
pipe can be lifted off after any screw or other attached devices  
are removed. Dispose of the draft hood. The new water  
heater has the draft hood which must be used for proper  
operation.  
6. If you have copper piping to the water heater, the two copper  
water pipes can be cut with a hacksaw approximately four  
inches away from where they connect to the water heater.  
This will avoid cutting off pipes too short. Additional cuts can  
be made later if necessary. Disconnect the temperature-  
pressure relief valve drain line. When the water heater is  
drained, disconnect the hose from the drain valve. Close the  
drain valve. The water heater is now completely disconnected  
and ready to be removed, see Figure 5.  
FIGURE1.  
1. Turn “OFF” the gas supply to the  
water heater.  
If the main gas line Shut-off valve  
serving all gas appliances is  
used, also shut “OFF” the gas at  
each appliance. Leave all gas  
appliances shut “OFF” until the  
water heater installation is  
completed, see Figures 1 and 2.  
FIGURE2.  
FIGURE3.  
FIGURE5.  
2. Turn “OFF” the water supply to the  
water heater at the water shut off  
valve or water meter. Some  
installations require that the water  
be turned off to the entire house,  
see Figures 1 and 3.  
If you have galvanized pipe to the water heater, loosen the  
two galvanized pipes with a pipe wrench at the union in each  
line. Also disconnect the piping remaining to the water heater.  
These pieces should be saved since they may be needed  
when reconnecting the new water heater. Disconnect the  
temperate-pressure relief valve drain line. When the water  
heater is drained, disconnect the hose from the drain valve.  
Close the drain valve. The water heater is now completely  
disconnected and ready to be removed. Mineral buildup or  
sediment may have accumulated in the old water heater.  
This causes the water heater to be much heavier than normal  
and this residue, if spilled out, could cause staining, see  
Figure 6.  
3. Check again to make sure the gas supply is “OFF” to the  
water heater. Then disconnect the gas supply connection  
from the gas control valve.

MIXING VALVE USAGE  
FIGURE8.  
This appliance has been design certified as complying with  
HOTTER WATER CAN SCALD:  
American National Standard/CSA Standard for water heaters  
and is considered suitable for:  
Water heaters are intended to produce hot water. Water heated  
to a temperature which will satisfy space heating, clothes  
washing, dish washing, and other sanitizing needs can scald  
and permanently injure you upon contact. Some people are  
more likely to be permanently injured by hot water than others.  
These include the elderly, children, the infirm, or physically/  
mentally handicapped. If anyone using hot water in your home  
fits into one of these groups or if there is a local code or state  
law requiring a certain temperature water at the hot water tap,  
then you must take special precautions. In addition to using the  
lowest possible temperature setting that satisfies your hot water  
needs, a means such as a *Mixing Valve, shall be used at the  
hot water taps used by these people or at the water heater.  
Mixing valves are available at plumbing supply or hardware  
stores. See Figure 8. Valves for reducing point of use temperature  
by mixing cold and hot water are also available. Consult Maytag  
Customer Service (1-800-788-8899). Follow mixing valve  
manufacturer’s instructions for installation of the valves. Before  
changing the factory setting on the thermostat, read the  
“Temperature Regulation” section in this manual, see Figures  
22 and 23 on page 20.

LOCATING THE NEW WATER HEATER  
Facts to Consider About the Location  
•
Devices that will turn off the gas supply to a gas water heater  
while at the same time shutting off its water supply.  
Carefully choose an indoor location for the new water heater,  
because the placement is a very important consideration for  
the safety of the occupants in the building and for the most  
economical use of the appliance. This water heater is not for  
use in manufactured (mobile) homes or outdoor installation.  
Whether replacing an old water heater or putting the water heater  
in a new location, the following critical points must be observed:  
•
Select a location indoors as close as practical to the gas  
vent or chimney to which the water heater vent is going to be  
connected, and as centralized with the water piping system  
as possible.  
•
Selected location must provide adequate clearances for  
servicing and proper operation of the water heater.  
INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQUIDS  
(VAPORS) ARE LIKELY TO BE PRESENT OR STORED  
(GARAGES, STORAGE AND UTILITY AREAS, ETC.):  
Flammable liquids (such as gasoline, solvents, propane [LP or  
butane, etc.] and other substances such as adhesives, etc.)  
emit flammable vapors which can be ignited by a gas water  
heater’s pilot light or main burner. The resulting flashback and  
fire can cause death or serious burns to anyone in the area.  
Even though this water heater is a flammable vapors ignition  
resistant water heater and is designed to reduce the chances  
of flammable vapors being ignited, gasoline and other  
flammable substances should never be stored or used in the  
same vicinity or area containing a gas water heater or other  
open flame or spark producing appliance.  
Installation of the water heater must be accomplished in such a  
manner that if the tank or any connections should leak, the flow  
will not cause damage to the structure. For this reason, it is not  
advisable to install the water heater in an attic or upper floor.  
When such locations cannot be avoided, a suitable drain pan  
should be installed under the water heater. Drain pans are  
available at your local hardware store. Such a drain pan must  
have a minimum length and width of at least 2 inches (51 mm)  
greater that the water heater dimensions and must be piped to  
an adequate drain. The pan must not restrict combustion air  
flow.  
Also, the water heater must be located and/or protected so it is  
not subject to physical damage by a moving vehicle.  
Water heater life depends upon water quality, water pressure  
and the environment in which the water heater is installed. Water  
heaters are sometimes installed in locations where leakage  
may result in property damage, even with the use of a drain pan  
piped to a drain. However, unanticipated damage can be reduced  
or prevented by a leak detector or water shut-off device used in  
conjunction with a piped drain pan. These devices are available  
from some plumbing supply wholesalers and retailers, and  
detect and react to leakage in various ways:  
•
•
•
Sensors mounted in the drain pan that trigger an alarm or  
turn off the incoming water to the water heater when leakage  
is detected.  
This water heater must not be installed directly on carpeting.  
Carpeting must be protected by metal or wood panel beneath  
the appliance extending beyond the full width and depth of the  
appliance by at least 3 inches (76.2 mm) in any direction, or if  
the appliance is installed in an alcove or closet, the entire floor  
must be covered by the panel. Failure to heed this warning may  
result in a fire hazard.  
Sensors mounted in the drain pan that turn off the water  
supply to the entire home when water is detected in the drain  
pan.  
Water supply shut-off devices that activate based on the  
water pressure differential between the cold water and hot  
water pipes connected to the water heater.

If this water heater will be used in beauty shops, barber shops,  
cleaning establishments, or self-service laundries with dry  
cleaning equipment, it is imperative that the water heater or  
water heaters be installed so that combustion and ventilation  
air be taken from outside these areas.  
Propellants of aerosol sprays and volatile compounds,  
(cleaners, chlorine based chemicals, refrigerants, etc.) in  
addition to being highly flammable in many cases, will also  
change to corrosive hydrochloric acid when exposed to the  
combustion products of the water heater. The results can be  
hazardous, and also cause product failure.  
Minimum clearances between the water heater and  
combustible construction are 0 inch at the sides and rear, 4  
inches (102 mm) at the front, and 6 inches (153 mm) from the  
vent pipe. Clearance from the top of the jacket is 12 inches  
(305 mm) on most models. Note that a lesser dimension may  
be allowed on some models, refer to the label attached adjacent  
to the gas control valve on the water heater, see Figure 9.  
Insulation Blankets  
• Do not obstruct water heater air  
intake with insulating blanket.  
• Gas and carbon monoxide  
detectors are available.  
• Install water heater in accordance  
with the instruction manual.  
FIGURE9.  
Insulation blankets available to the general public for external  
use on gas water heaters are not necessary with Maytag  
products. The purpose of an insulation blanket is to reduce the  
standby heat loss encountered with storage tank heaters. Your  
Maytag water heater meets or exceeds the National Appliance  
Energy Conservation Act standards with respect to insulation  
and standby loss requirements, making an insulation blanket  
unnecessary.  
•
•
•
Install water heater in accordance  
with the instruction manual and  
NFPA54.  
To avoid injury, combustion and  
ventilation air must be taken from  
outdoors.  
Do not place chemical vapor  
emitting products near water  
heater.  
Should you choose to apply an insulation blanket to this heater,  
you should follow these instructions (See Figure 7 for  
identification of components mentioned below). Failure to follow  
these instructions can restrict the air flow required for proper  
combustion, potentially resulting in fire, asphyxiation, serious  
personal injury or death.  
A gas water heater cannot operate properly without the correct  
amount of air for combustion. Do not install in a confined area  
such as a closet, unless you provide air as shown in the  
Locating The New Water Heater section. Never obstruct the  
flow of ventilation air. If you have any doubts or questions at all,  
call your gas supplier. Failure to provide the proper amount of  
combustion air can result in a fire or explosion and cause  
death, serious bodily injury, or property damage.  
•
•
•
•
•
•
Do not apply insulation to the top of the water heater, as this  
will interfere with safe operation of the draft hood.  
Do not cover the outer door, thermostat or temperature &  
pressure relief valve.  
Do not allow insulation to come within 2” (50.8 mm) of the  
floor to prevent blockage of combustion air flow to the burner.  
Do not cover the instruction manual. Keep it on the side of  
the water heater or nearby for future reference.  
Do obtain new warning and instruction labels from Maytag  
for placement on the blanket directly over the existing labels.  
Do inspect the insulation blanket frequently to make certain  
FIGURE10.  
it does not sag, thereby obstructing combustion air flow.

top and one commencing within 12 inches (30 cm) from the  
bottom of the enclosure. The openings shall communicate  
directly, or by ducts, with the outdoors or spaces (crawl or attic)  
that freely communicate with the outdoors.  
Combustion Air and Ventilation for  
Appliances Located in Unconfined Spaces  
UNCONFINED SPACE is space whose volume is not less than  
50 cubic feet per 1,000 Btu per hour (4.8 m3 per kW) of the  
aggregate input rating of all appliances installed in that space.  
Rooms communicating directly with the space in which the  
appliances are installed, through openings not furnished with  
doors, are considered a part of the unconfined space.  
In unconfined spaces in buildings, infiltration may be adequate

Special Conditions Created by Mechanical Exhausting or  
Fireplaces: operation of exhaust fans, ventilation systems,  
clothes dryers or fireplaces may create conditions requiring  
special attention to avoid unsatisfactory operation of installed  
gas utilization equipment.  
This water heater shall not be connected to any heating systems  
or component(s) used with a non-potable water heating  
appliance.  
Water Piping  
Toxic chemicals, such as those used for boiler treatment shall  
not be introduced into this system.  
Water supply systems may, because of such events as high  
line pressure, frequent cut-offs, the effects of water hammer  
among others, have installed devices such as pressure  
reducing valves, check valves, back flow preventers, etc. to  
control these types of problems. When these devices are not  
equipped with an internal by-pass, and no other measures are  
taken, the devices cause the water system to be closed. As  
water is heated, it expands (thermal expansion) and closed  
systems do not allow for the expansion of heated water.  
The water within the water heater tank expands as it is heated  
and increases the pressure of the water system. If the relieving  
point of the water heater’s temperature-pressure relief valve is  
reached, the valve will relieve the excess pressure. The  
temperature-pressure relief valve is not intended for the  
constant relief of thermal expansion. This is an unacceptable  
condition and must be corrected. It is recommended that any  
devices installed which could create a closed system have a  
by-pass and/or the system have an expansion tank to relieve  
the pressure built by thermal expansion in the water system.  
Refer to the Thermal Expansion section under Troubleshooting  
Guide or contact local plumbing authority or call Maytag  
Customer Service at 1-800-788-8899 for an authorized  
installer on how to control this situation.  
HOTTER WATER CAN SCALD:  
Water heaters are intended to produce hot water. Water heated  
to a temperature which will satisfy space heating, clothes  
washing, dish washing, cleaning and other sanitizing needs  
can scald and permanently injure you upon contact. Some  
people are more likely to be permanently injured by hot water  
than others. These include the elderly, children, the infirm, or  
physically/mentally handicapped. If anyone using hot water in  
your home fits into one of these groups or if there is a local  
code or state law requiring a certain temperature water at the  
hot water tap, then you must take special precautions. In  
addition to using the lowest possible temperature setting that

Look at the top of the water heater. The cold water inlet is  
marked “COLD”. Put two or three turns of teflon tape around  
the threaded end of the threaded-to-sweat coupling and  
around both ends of the 3/4” NPT threaded nipple. Using  
standard pipe fittings, connect the cold water pipe to the  
cold water inlet of the water heater.  
NOTE: This water heater is super insulated to minimize  
heat loss from the tank. Further reduction in heat loss  
can be accomplished by insulating the hot water lines  
from the water heater.  
T & P Valve and Pipe Insulation  
NOTE: To protect against untimely corrosion of hot and cold  
water fittings, it is strongly recommended that di-electric  
unions or couplings be installed on this water heater when  
connected to copper pipe.  
Remove insulation for T & P valve and pipe connections from  
carton.  
NOTE: The secondary anode rod/hot outlet nipple and the  
cold inlet nipple are packaged separately with the water  
heater. The above parts must be installed in the appropriate  
HOT and COLD water connections.  
Figure 16 shows the typical attachment of the water piping to  
the water heater. The water heater is equipped with 3/4” NPT  
water connections for 40 and 50 gallon models.  
FIGURE16A.  
Fit pipe insulation over the incoming cold water line and the hot  
water line. Make sure that the insulation is against the top  
cover of the heater.  
Fit T & P valve insulation over valve. Make sure that the insulation  
does not interfere with the lever of the T & P valve.  
Secure all insulation using tape.  
Temperature-Pressure Relief Valve  
• Temperature-pressure relief valve  
must comply with ANSI Z21.22  
and ASME code.  
• Properly sized temperature-relief  
valve must be installed in opening  
provided.  
• Can result in overheating and  
excessive tank pressure.  
FIGURE16.  
• Can cause serious injury or death.  
NOTE: If using copper tubing, solder tubing to an adapter  
before attaching the adapter to the cold water inlet  
connection. Do not solder the cold water supply line directly  
to the cold water inlet. It will harm the dip tube and damage  
the tank.  
This heater is provided with a properly certified combination  
temperature - pressure relief valve by the manufacturer.  
The valve is certified by a nationally recognized testing  
laboratory that maintains periodic inspection of production of  
listed equipment of materials as meeting the requirements for  
Relief Valves andAutomatic Gas Shut-off Devices for Hot Water  
Supply Systems, ANSI Z21.22 and the code requirements of  
ASME.  
•
Look at the top cover of the water heater. The water outlet is  
marked “HOT”. Put two or three turns of teflon tape around  
the threaded end of the threaded-to-sweat coupling and  
around both ends of the 3/4” NPT threaded nipple. Using  
standard pipe fittings, connect the hot water pipe to the hot  
water outlet on the water heater.

If replaced, the valve must meet the requirements of local  
codes, but not less than a combination temperature and  
pressure relief valve certified as indicated in the above  
paragraph.  
The Discharge Pipe:  
• Shall not be smaller in size than the outlet pipe size of the  
valve, or have any reducing couplings or other restrictions.  
The valve must be marked with a maximum set pressure not to  
exceed the marked hydrostatic working pressure of the water  
heater (150 psi = 1,035 kPa) and a discharge capacity not less  
than the water heater input rate as shown on the model rating  
plate.  
• Shall not be plugged or blocked.  
• Shall be of material listed for hot water distribution.  
• Shall be installed so as to allow complete drainage of both  
the temperature-pressure relief valve, and the discharge  
pipe.  
For safe operation of the water heater, the relief valve must not  
be removed from its designated opening nor plugged.  
• Shall terminate at an adequate drain.  
The temperature-pressure relief valve must be installed directly  
into the fitting of the water heater designed for the relief valve.  
Position the valve downward and provide tubing so that any  
discharge will exit only within 6 inches (153 mm) above, or at  
any distance below the structural floor. Be certain that no contact  
is made with any live electrical part. The discharge opening  
must not be blocked or reduced in size under any  
circumstances. Excessive length, over 30 feet (9.14 m), or use  
of more than four elbows can cause restriction and reduce the  
discharge capacity of the valve, see Figure 17.  
• Shall not have any valve between the relief valve and tank.  
No valve or other obstruction is to be placed between the relief  
valve and the tank. Do not connect tubing directly to discharge  
drain unless a 6 inch air gap is provided. To prevent bodily  
injury, hazard to life, or property damage, the relief valve must  
be allowed to discharge water in quantities should  
circumstances demand. If the discharge pipe is not connected  
to a drain or other suitable means, the water flow may cause  
property damage.  
The temperature-pressure relief valve must be manually  
operated at least once a year. Caution should be taken to  
ensure that (1) no one is in front of or around the outlet of the  
temperature-pressure relief valve discharge line, and (2) the  
water manually discharged will not cause any bodily injury or  
property damage because the water may be extremely hot.  
If after manually operating the valve, it fails to completely reset  
and continues to release water, immediately close the cold  
water inlet to the water heater, follow the draining instructions,  
and replace the temperature-pressure relief valve with a new  
one.  
Filling the Water Heater  
FIGURE17.  
Never use this water heater unless it is completely full of water.  
To prevent damage to the tank, the tank must be filled with  
water. Water must flow from the hot water faucet before turning  
“ON” gas to the water heater.  
To fill the water heater with water:  
•
Close the water heater drain valve by turning the handle to  
the right (clockwise). The drain valve is on the lower front of  
the water heater.

proper venting for your water heater from the vent tables in the  
current edition of the National Fuel Gas Code ANSI Z223.1/  
NFPA 54.  
To insure complete filling of the tank, allow air to exit by  
opening the nearest hot water faucet. Allow water to run  
until a constant flow is obtained. This will let air out of the  
water heater and the piping.  
Periodically check the venting system for signs of obstruction  
or deterioration and replace if needed.  
The combustion and ventilation air flow must not be obstructed.  
•
Check all water piping and connections for leaks. Repair  
as needed.  
The water heater with draft hood installed must be connected  
to a chimney or listed vent pipe system, which terminates to  
the outdoors. Never operate the water heater unless it is vented  
to the outdoors and has adequate air supply to avoid risks of  
improper operation, explosion or asphyxiation.  
Venting  
VENT DAMPERS - Any vent damper, whether it is operated  
thermally or otherwise must be removed if its use inhibits proper  
drafting of the water heater.  
•
For proper draft hood attachment, the draft hood legs may  
be angled slightly inward.  
•
Place the draft hood legs in the receiving holes on the top of  
the water heater. The legs will snap in the holes to give a  
tight fit. Secure two legs to top with sheet metal screws.  
Thermally Operated Vent Dampers: Gas-fired water heaters  
having thermal efficiency in excess of 80% may produce a  
relatively low flue gas temperature. Such temperatures may  
not be high enough to properly open thermally operated vent  
dampers. This would cause spillage of the flue gases and  
may cause carbon monoxide poisoning.  
•
Place the vent pipe over the draft hood. With the vent pipe in  
position, drill a small hole through both the vent pipe and  
draft hood. Secure them together with a sheet metal screw,  
see Figure 18.  
Vent dampers must bear evidence of certification as complying  
with the current edition of the American National Standard  
ANSI Z21.68 (ANSI Z21.66 & 67, respectively, cover electrically  
and mechanically actuated vent dampers). Before installation  
of any vent damper, consult your Maytag Customer Service  
Center at 1-800-788-8899 or the local gas supplier for further  
information.  
Obstructed or deteriorated vent systems may present serious  
health risk or asphyxiation.  
FIGURE18.  
The vent pipe from the water heater must be no less than the  
diameter of the draft hood outlet on the water heater and must  
slope upward at least 1/4 inch per linear foot (21 mm per meter),  
see Figure 19.  
To insure proper venting of this gas-fired water heater, the  
correct vent pipe diameter must be utilized. Any additions or  
deletions of other gas appliances on a common vent with this  
water heater may adversely affect the operation of the water

heater.  
Consult your Maytag Service Center at  
1-800-788-8899 or gas supplier if any such changes are  
planned.  
All vent gases must be completely vented to the outdoors of the  
structure (dwelling). Install only the draft hood provided with  
the new water heater and no other draft hood.  
For proper venting in certain installations, a larger diameter  
vent pipe may be necessary. Consult your Maytag Customer  
Service Center or gas supplier to aid you in determining the  
Vent pipes must be secured at each joint with sheet metal  
screws.

There must be a minimum of 6 inches (153 mm) clearance  
between single wall vent pipe and any combustible material.  
Fill and seal any clearance between single wall vent pipe and  
combustible material with mortar mix, cement, or other  
noncombustible substance. For other than single wall, follow  
vent pipe manufacturer’s clearance specifications. To insure  
a tight fit of the vent pipe in a brick chimney, seal around the

plate is for the purpose of input adjustment. If the gas control  
valve is subjected to pressures exceeding 1/2 pound per square  
inch (3.5kPa), the damage to the gas control valve could result  
in a fire or explosion from leaking gas.  
If the main gas line Shut-off serving all gas appliances is used,  
also turn “OFF” the gas at each appliance. Leave all gas  
appliances shut “OFF” until the water heater installation is  
complete.  
A gas line of sufficient size must be run to the water heater.  
Consult the current edition of National Fuel Gas Code ANSI  
Z223.1/NFPA 54 and your gas supplier concerning pipe size.  
There must be:  
•
A readily accessible manual shut off valve in the gas supply  
line serving the water heater, and  
•
A drip leg (sediment trap) ahead of the gas control valve to  
help prevent dirt and foreign materials from entering the  
gas control valve.  
•
A flexible gas connector or a ground joint union between the  
shut off valve and control valve to permit servicing of the unit.  
Be sure to check all the gas piping for leaks before lighting the  
water heater. Use a soapy water solution, not a match or open  
flame. Rinse off soapy solution and wipe dry.  
The minimum inlet gas pressure shown on the rating plate is  
that which will permit firing at the rated input.  
Failure to have required clearances between vent piping and  
combustible material will result in a fire hazard.  
Be sure vent pipe is properly connected to prevent escape of  
dangerous flue gases which could cause deadly asphyxiation.  
Chemical vapor corrosion of the flue and vent system may  
occur if air for combustion contains certain chemical vapors.  
Spray can propellants, cleaning solvents, refrigerator and air  
conditioner refrigerants, swimming pool chemicals, calcium  
and sodium chloride, waxes, bleach and process chemicals  
are typical compounds which are potentially corrosive.  
Gas Piping  
If a standard model is installed above 3,300 feet (1,006 m) or a  
high altitude model is installed above 5,500 feet (1,676 m) the  
input rating should be reduced at the rate of 4 percent for each  
1,000 feet (305 m ) above sea level which requires replacement  
of the burner orifice in accordance with National Fuel Gas Code  
ANSI Z223.1/NFPA 54. Contact Maytag Customer Service  
Center at 1-800-788-8899 or your local gas supplier or call  
for further information.  
Failure to replace the standard orifice with a high altitude orifice  
when installed at elevations above 3,300 feet (1,006 m) or  
above 5,500 feet (1,676 m) for high altitude model could result  
in improper and inefficient operation of the appliance, producing  
carbon monoxide gas in excess of safe limits, which could  
result in serious injury or death. Contact Maytag Customer  
Service at 1-800-788-8899 or your local gas supplier for any  
specific changes which may be required in your area.  
Make sure the gas supplied is the same type listed on the  
model rating plate. The inlet gas pressure must not exceed  
14 inch water column (2.6kPa) for natural and propane gas  
(L.P.) gas. The minimum inlet gas pressure listed on the rating

Contaminants in the gas lines may cause improper operation  
of the gas control valve that may result in fire or explosion.  
Before attaching the gas line be sure that all gas pipe is clean  
on the inside. To trap any dirt or foreign material in the gas  
supply line, a drip leg (sometimes called a sediment trap)  
must be incorporated in the piping. The drip leg must be readily  
accessible. Install in accordance with the Gas Piping section.  
Refer to the current edition of the National Fuel Gas Code,  
ANSI Z223.1/NFPA54.  
A sediment trap shall be installed as close to the inlet of the  
water heater as practical at the time of water heater installation.  
The sediment trap shall be either a tee fitting with a capped  
nipple in the bottom outlet or other device recognized as an  
effective sediment trap. If a tee fitting is used, it shall be installed  
in conformance with one of the methods of installation, shown  
in Figures 20 and 21.  
Use pipe joint compound or teflon tape marked as being  
resistant to the action of petroleum (Propane [L.P.]) gases.  
The appliance and its gas connection must be leak tested  
before placing the appliance in operation.  
The appliance and its individual Shut-off valve shall be  
disconnected from the gas supply piping system during any  
pressure testing of that system at test pressures in excess of  
1/2 pound per square inch (3.5kPa). It shall be isolated from  
the gas supply piping system by closing its individual manual  
Shut-off valve during any pressure testing of the gas supply  
piping system at test pressures equal to or less than 1/2 pound  
per square inch (3.5kPa).  
Connecting the gas piping to the gas control valve of the water  
heater can be accomplished by either of the two methods,  
shown in Figures 20 and 21.

installation of the valves. Before changing the factory setting  
on the thermostat, read the Temperature Regulation section in  
this manual, see Figures 22 and 23.  
Temperature Regulation  
Due to the nature of the typical gas water heater, the water  
temperature in certain situations may vary up to 30F° (16.7 C°)  
higher or lower at the point of use such as, bathtubs, showers,  
sink, etc.  
Never allow small children to use a hot water tap, or to draw  
their own bath water. Never leave a child or handicapped person  
unattended in a bathtub or shower.  
Any water heater’s intended purpose is to heat water. Hot  
water is needed for cleansing, cleaning, and sanitizing (bodies,  
dishes, clothing). Untempered hot water can present a scald  
hazard. Depending on the time element, and the people  
involved (adults, children, elderly, infirm, etc.) scalding may occur  
at different temperatures.  
NOTE: A water temperature range of 120°F-140°F (49°C-60°C)  
is recommended by most dishwasher manufacturers.  
The thermostat of this water heater has been factory set at its  
lowest position (PILOT LIGHTING). It is adjustable and must  
be reset to the desired temperature setting to reduce the risk of  
scald injury. The mark ( ) indicative of approximately 120°F  
(49°C) is preferred starting point. Some states have a  
requirement for a lower setting.  
Turn the water temperature dial clockwise (

Should overheating occur or the gas supply fail to shut off, turn  
off the manual gas control valve to the appliance.  
HOTTER WATER CAN SCALD: Water heaters are intended to  
produce hot water. Water heated to a temperature which will  
satisfy space heating, clothes washing, dish washing, and  
other sanitizing needs can scald and permanently injure you  
upon contact. Some people are more likely to be permanently  
injured by hot water than others. These include the elderly,  
children, the infirm, or physically/mentally handicapped. If  
anyone using hot water in your home fits into one of these  
groups or if there is a local code or state law requiring a certain  
temperature water at the hot water tap, then you must take  
special precautions. In addition to using the lowest possible  
temperature setting that satisfies your hot water needs, a  
means such as a mixing valve, shall be used at the hot water  
taps used by these people or at the water heater. Mixing valves  
are available at plumbing supply or hardware stores, see  
Figure 8 on page 9 and Figure 15 on page 13. Valves for  
reducing point of use temperature by mixing cold and hot water  
are also available. Consult Maytag Customer Service

SERVICE AND MAINTENANCE  
Tank (Sediment) Cleaning  
Burner Inspection  
Flood damage to a water heater may not be readily visible or  
immediately detectable. However, over a period of time a  
flooded water heater will create dangerous conditions which  
can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY  
DAMAGE. Contact the Maytag dealer from whom the appliance  
was purchased or call Maytag Customer Service at  
1-800-788-8899 for an authorized servicer to replace a  
flooded water heater. Do not attempt to repair the unit! It  
must be replaced!  
Sediment build-up on the tank bottom may create varying  
amount of noise, if left in the tank will cause permanent tank  
failure. In some water areas, sediment can be removed by  
draining off approximately one gallon of water each month.  
Vent System Inspection  
At least once a year a visual inspection should be made of the  
main burner and pilot burner, see Figure 24.  
You should check for sooting. Soot is not normal and will impair  
proper combustion.  
•
•
Flue gases may escape if vent pipe  
is not connected.  
Soot build-up indicates a problem that requires correction  
before further use. Turn “OFF” gas to water heater and  
leave off until repairs are made, because failure to correct the  
cause of the sooting can result in a fire causing death, serious  
injury, or property damage.  
Be alert for obstructed, sooted or  
deteriorated vent system to avoid  
serious injury or death.  
•
•
Do not store corrosive chemicals  
in vicinity of water heater.  
Chemical corrosion of flue and vent  
system can cause serious injury or  
death  
FIGURE24.  
At least once a year a visual inspection should be made of the  
venting system. You should look for:  
Burner Cleaning

•
•
Obstructions which could cause improper venting. The  
combustion and ventilation air flow must not be obstructed.  
Damage or deterioration which could cause improper  
venting or leakage of combustion products.  
Rusted flakes around top of water heater.  
Be sure the vent piping is properly connected to prevent escape  
of dangerous flue gasses which could cause deadly  
asphyxiation.  
Obstructions and deteriorated vent systems may present  
serious health risk or asphyxiation.  
Chemical vapor corrosion of the flue and vent system may  
occur if air for combustion contains certain chemical vapors.  
Spray can propellants, cleaning solvents, refrigerator and air  
conditioner refrigerants, swimming pool chemicals, calcium  
and sodium chloride, waxes, bleach and process chemicals  
are typical compounds which are potentially corrosive.  
In the event your burner needs cleaning, following these  
instructions:  
If after inspection of the vent system you found sooting or  
deterioration, something is wrong. Call Maytag Customer  
Service at 1-800-788-8899 for an authorized servicer or your  
local gas supplier to correct the problem and clean or replace  
the flue and venting before resuming operation of the water  
heater.  
If inspection of the burner shows that cleaning is required, turn  
the gas control knob clockwise (  
depressing slightly.  
) to the “OFF” position,  
NOTE: The knob cannot be turned from “PILOT” to “OFF”  
unless knob is depressed slightly. DO NOT FORCE.

qualified technician. At a minimum, the anode(s) should be  
checked annually after the warranty period.  
The burner needs to be removed for cleaning. Call Maytag  
Customer Service at 1-800-788-8899 for an authorized  
servicer to remove and clean the burner and correct the  
problem that required the burner to be cleaned.  
Temperature-Pressure Relief Valve Operation  
Housekeeping  
The temperature-pressure relief valve must be manually  
operated at least once a year.  
Vacuum around base of water heater for dust, dirt, and lint on a  
regular basis.  
When checking the temperature-pressure relief valve operation,  
make sure that (1) no one is in front of or around the outlet of  
the temperature-pressure relief valve discharge line, and (2)  
that the water discharge will not cause any property damage,  
as the water may be extremely hot, see Figure 25.  
AT LEAST ONCE EVERY SIX MONTHS A  
VISUAL INSPECTION SHOULD BE MADE OF  
THE AIR INTAKE SCREEN. CLEAN IF LINT  
ACCUMULATIONS ARE NOTICED.  
INSTALLED IN SUITABLEAREA: To insure sufficient ventilation  
and combustion air supply, proper clearances from the water  
heater must be maintained. See Facts to Consider About the  
Location section. Combustible materials such as clothing,  
cleaning materials, or flammable liquids, etc. must not be  
placed against or adjacent to the water heater which can cause  
a fire.  
FIGURE 25.  
If after manually operating the valve, it fails to completely reset  
and continues to release water, immediately close the cold  
water inlet to the water heater, follow the draining instructions,  
and replace the temperature-pressure relief valve with a new  
one.  
If the temperature-pressure relief valve on the appliance weeps  
or discharges periodically, this may be due to thermal  
expansion. You may have a check valve installed in the water  
line or a water meter with a check valve. Consult Maytag  
Customer Service at 1-800-788-8899 for further information.  
Do not plug the temperature-pressure relief valve.  
Anode Rod Inspection  
Draining  
The anode rod is used to protect the tank from corrosion. Most  
hot water tanks are equipped with an anode rod. The  
submerged rod sacrifices itself to protect the tank. Instead of  
corroding the tank, water ions attack and eat away the anode  
rod. This does not affect the water’s taste or color. The rod  
must be maintained to keep the tank in operating condition.  
Anode deterioration depends on water conductivity, not  
necessarily water condition. A corroded or pitted anode rod  
indicates high water conductivity and should be checked and/  
or replaced more often than an anode rod that appears to be  
intact. Replacement of a depleted anode rod can extend the  
life of your water heater. Inspection should be conducted by a  
The water heater should be drained if being shut down during  
freezing temperatures. Also periodic draining and cleaning of  
sediment from the tank may be necessary.

TROUBLESHOOTING  
particularly high efficiency models where flue temperatures  
are lower.  
Start Up Conditions  
Draft Hood Operation  
•
Large amounts of hot water are used in a short time and  
the refill water in the tank is very cold.  
Check draft hood operation by performing a worst case  
depressurization of the building. With all doors and windows  
closed, and with all air handling equipment and exhaust fans  
operating, such as furnaces, clothes dryers, range hoods and  
bathroom fans, a match flame should still be drawn into the  
draft hood of the water heater with its burner firing. If the flame  
is not drawn toward the draft hood, shut off the water heater  
and make necessary air supply changes to correct.  
Moisture from the products of combustion condense on the  
cooler tank surfaces and form drops of water which may fall  
onto the burner or other hot surfaces to produce a “sizzling” or  
“frying” noise.  
Excessive condensation can cause pilot outage due to water  
running down the flue tube onto the main burner and putting  
out the pilot.  
Because of the suddenness and amount of water,  
condensation water may be diagnosed as a “tank leak”. After  
the water in the tank warms up (about 1-2 hours), the condition  
should disappear.  
Condensation  
Whenever the water heater is filled with cold water, some  
condensate will form while the burner is on. A water heater  
may appear to be leaking when in fact the water is condensation.  
This usually happens when:  
Do not assume the water heater is leaking until there has  
been enough time for the water in the tank to warm up.  
An undersized water heater will cause more condensation.  
The water heater must be sized properly to meet the family’s  
demands for hot water including dishwashers, washing  
machines and shower heads.

A new water heater is filled with cold water for the first time.  
Burning gas produces water vapor In water heaters,

Excessive condensation may be noticed during the winter and  
early spring months when incoming water temperatures are at  
their lowest.  
Operational Conditions  
Smelly Odor  
Good venting is essential for a gas fired water heater to operate  
properly as well as to carry away products of combustion and  
water vapor.  
In each water heater there is installed at least one anode rod  
(see parts section) for corrosion protection of the tank. Certain  
water conditions will cause a reaction between this rod and  
the water. The most common complaint associated with the  
anode rod is one of a “rotten egg smell”. This odor is derived  
from hydrogen sulfide gas dissolved in the water. The smell is  
the result of four factors which must all be present for the odor  
to develop:  
Smoke / Odor  
It is not uncommon to experience a small amount of smoke  
and odor during the initial start-up. This is due to burning off of  
oil from metal parts, and will disappear in a short while.  
•
•
•
a concentration of sulfate in the supply water.  
little or no dissolved oxygen in the water.  
Thermal Expansion  
a sulfate reducing bacteria within the water heater. (This  
harmless bacteria is non-toxic to humans.)  
•
an excess of active hydrogen in the tank. This is caused by  
the corrosion protective action of the anode.  
Smelly water may be eliminated or reduced in some water  
heater models by replacing the anode(s) with one of less active  
material, and then chlorinating the water heater tank and all  
hot water lines. Contact Maytag Customer Service at  
1-800-788-8899 for further information concerning an Anode  
Replacement Kit and this Chlorination Treatment.  
Water supply system may, because of such events as high line  
pressure, frequent cut-offs, the effects of water hammer among  
others, have installed devices such as pressure reducing  
valves, check valves, back flow preventers, etc., to control these  
types of problems. When these devices are not equipped with  
an internal by-pass, and no other measures are taken, the  
devices cause the water system to be closed. As water is  
heated, it expands (thermal expansion) and closed systems  
do not allow for the expansion of heated water.  
If the smelly water persists after the anode replacement and  
chlorination treatment, we can only suggest that chlorination  
or aeration of the water supply be considered to eliminate the  
water problem.  
Do not remove the anode leaving the tank unprotected. By  
doing so, all warranty on the water heater tank is voided.  
“AIR” In Hot Water Faucets  
The water within the water heater tank expands as it is heated  
and increases the pressure of the water system. If the relieving  
point of water heater’s temperature-pressure relief valve is  
reached, the valve will relief the excess pressure. The  
temperature-pressure relief valve is not intended for the  
constant relief of thermal expansion. This is an unacceptable  
condition and must be corrected.  
It is recommended that any devices installed which could create  
a closed system have a by-pass and/or the system have an  
expansion tank or device to relieve the pressure built by thermal  
expansion in the water system. Thermal expansion tanks are  
available for ordering through the Maytag Customer Service  
Center (1-800-788-8899). Contact the local plumbing inspector,  
water supplier and/or call Maytag Customer Service at  
1-800-788-8899 for assistance in controlling these situations.  
HYDROGEN GAS: Hydrogen gas can be produced in a hot  
water system that has not been used for a long period of time  
(generally two weeks or more). Hydrogen gas is extremely  
flammable and explosive. To prevent the possibility of injury  
under these conditions, we recommend the hot water faucet,  
located farthest away, be opened for several minutes before  
any electrical appliances which are connected to the hot water  
system are used (such as a dishwasher or washing machine).  
If hydrogen gas is present, there will probably be an unusual  
sound similar to air escaping through the pipe as the hot water  
faucet is opened. There must be no smoking or open flame  
near the faucet at the time it is open.  
Strange Sounds  
Possible noises due to expansion and contraction of some  
metal parts during periods of heat-up and cool-down do not  
represent harmful or dangerous conditions.  
Condensation causes sizzling and popping within the burner  
area during heating and cooling periods and should be  
considered normal. See Condensation section.

H. Combustion products contain water vapor which can  
condense on the cooler surfaces of the tank. Droplets form  
and drip onto the burner or run on the floor. This is common  
at the time of start-up after installation and when incoming  
water is cold.  
High Temperature Shut Off System  
This water heater is equipped with an automatic gas Shut-off  
system. This system works when high water temperatures  
are present. Turn “OFF” the entire gas supply to the water  
heater. The high temperature Shut-off is built into the gas control  
valve. It is non-resettable. If the high temperature Shut-off  
activates, the gas control valve must be replaced. Call Maytag  
Customer Service at 1-800-788-8899 for an authorized  
servicer.  
I. Water in the water heater bottom or on the floor may be from  
condensation, loose connections, or the relief valve.  
DO NOT replace the water heater until a full inspection of all  
possible water sources is made and necessary corrective  
steps taken.  
Leakage Checkpoints  
Leakage from other appliances, water lines, or ground seepage  
should also be checked.  
*
To check where threaded portion enters tank, insert cotton  
swab between jacket opening and fitting. If cotton is wet,  
follow “Draining” instructions in the Periodic Maintenance  
section and then remove fitting. Put pipe dope or teflon tape  
on the threads and replace. Then follow Filling the Water  
Heater instructions in the Installing the New Water Heater  
section.  
Read this manual first. Then before checking the water heater  
make sure the gas supply has been turned “OFF”, and never  
turn the gas “ON” before the tank is completely full of water.  
Never use this water heater unless it is completely filled with  
water. To prevent damage to the tank, the tank must be filled  
with water. Water must flow from the hot water faucet before  
turning “ON” gas to the water heater, see Figure 28.  
A. Water at the draft hood is water vapor which has condensed  
out of the combustion products. This is caused by a problem  
in the vent. Call Maytag Customer Service at  
1-800-788-8899 for an authorized servicer.  
B. *Condensation may be seen on pipes in humid weather or  
pipe connections may be leaking.  
C. *The anode rod fitting may be leaking.  
D. Small amounts of water from temperature-pressure relief  
valve may be due to thermal expansion or high water  
pressure in your area.  
E. *The temperature-pressure relief valve may be leaking at  
the tank fitting.  
F. Water from a drain valve may be due to the valve being  
slightly opened.  
G. *The drain valve may be leaking at the tank fitting.
